Systems and methods for managing pneumatic pathways in integrated multilayer wound dressings
A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.
1. A system for providing instillation fluid to a deep abdominal wound, the system comprising:
an instillation module defining a first surface and a second, abdominal contents-facing surface, the instillation module including a distribution hub configured to receive instillation fluid from an instillation fluid source;
a connection structure comprising:
a first surface;
a second, abdominal contents-facing surface; and
a flow path extending between the first surface of the connection structure and the second surface of the connection structure, the flow path including an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module, the flow path defining an axis extending between the inlet and the outlet and configured to compress in a direction defined by the axis; and
a negative pressure manifold defining a first surface and a second, abdominal contents-facing surface, the second surface of the negative pressure manifold directly coupled to the first surface of the instillation module, and wherein the flow path extends through the negative pressure manifold such that the flow path is positioned within the negative pressure manifold.
2. The system of claim 1 , wherein at least a portion of the flow path is articulated to facilitate compression.
3. The system of claim 1 , wherein at least the flow path is configured to compress under negative pressure provided by a negative pressure source.
4. The system of claim 1 , wherein the second surface of the connection structure is secured to the first surface of the instillation module to provide a fluid-tight connection between the flow path and the instillation module.
5. The system of claim 1 , wherein the negative pressure manifold is formed of a compressible material and the connection structure is formed of the compressible material such that the negative pressure manifold and the connection structure collapse by substantially a same amount under negative pressure.
6. The system of claim 1 , further comprising a first connection plate including the first surface of the connection structure, a second connection plate including the second surface of the connection structure, and wherein the first connection plate, the second connection plate, and the flow path are integrally formed.
7. The system of claim 1 , further comprising a connection plate positioned adjacent the first surface of the connection structure, the connection plate including indicia for accurately positioning the instillation fluid conduit.
8. The system of claim 1 , wherein the first surface of the connection structure includes a first fluid-impermeable coating, the second surface of the connection structure includes a second fluid-impermeable coating, and the flow path includes a flow path fluid-impermeable coating.
9. The system of claim 1 , wherein the instillation module and the connection structure are positionable within an incision of the deep abdominal wound.
